Application filed January 9, 1915. SerialNo. 1,297.

, To all whom it may concern:

Be it known that-I, WILLIAM Gnus,'Jr., a

' citizen of the United States, residing at Chi- .cago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Antiskid Devices, of which the following'is a specification.

This Invention relates to a device for overi I coming or minimizing the tendency of a veand theprincipal object of the invention is hicle, particularly an automobile, to skid,

to provide an improved and simple device of thisclass which is readilyapplied'to the wheel without being wrapped entirely 'arou'nd,"or encircling, the entire wheel.

Affurther object of the invention is to provide'a simple device of this kind which can be applied-in sections to one or more .of the wheels so that anyiwheelcan be given more tractive effect, as desired.

Other objects will appear hereinafter.

' Figi 2 is a sectional view of the same; Fig.

3 is a-view taken. on the line 3-3 of Fig. 2,

and Fig; 4 is a perspective view of one of the stirrups.

" -jectionable for the reason that if they are -Anti-skid devices for automobiles are obused continuously the chains will wear at the y tires,' and most anti skid devices are designed effect.

1 to be used continously. There is seldom a necessity forthe continuous use of an antiskid device and the greatestnecessity is for an emergency use, as for example, when the wheels are in a mud-hole or in soft ground. where they do not have sufficient tractive In such a situation it is impossible.

to apply most of the anti-skid chains and it is customary to wrap a rope or chain about that portion of the wheel which'is above the mud-hole so that when the wheel slips around the wrapped chain or rope will en-' gage in the. soft ground and produce sulficient traction to enable the automobile to Since every unit is complete in itself it is not Specification of Letters Patent.

In the drawings-a portion o n' automobile wheel is shown con sing I fell y-6, a rim 7 to which a tire t is -s'eci edyanda The anti-skid device propei c'o, sistsof a pair of U-shaped clips or stirrups 10, each formed with a rounded loop 11 with ex tremities 12 and 13 bent out of the plane of the rounded portion and formed one with a hook 14.- and the other with an eye or closed loop 15. These stirrups are adapted to I straddle a spoke 9 and are seated thereabout by inserting them from opposite sides of the wheel with the extremities 12 and 13 e:-: tending outwardly in the direction of the tire. A chain section 16 is connected at one end to the closed loop of each stirrup and is adapted to be connected to the heck of the opposite-stirrup so that when the two stirrups are placed in position upon a single spoke they will be connected by two chain sections '16 extending over the tire of the Wheel.

As many separate devices can be applied to each wheel as there are spokes, but it is found in practice that one or two of them is suflicient for most ordinary conditions in actual practice. As the devices are easily removable they will not ordinarily be continuously used and consequently an automobile tire will not be damaged to as great an extent as with anti-skid chains which extend all around the wheel.

What I claim is: I

1. ,An automobile anti-skid device consisting of a pair of stirrups adapted to be seated from opposite sides of a wheel about the same spoke with the extremities of each stirrup projecting on the side opposite that from which it is seated, and chain sections connecting corresponding extremities of the opposite stirrups and extending over the tire of the wheel.

2. An anti-skid device for automobile wheels comprising apair of stirrups adapted to be seated about. a single spoke from opposite sides thereof each having looped Ircle tlietl1' o'pposite every spoke, and ifrinoi' e traction as extremities, one of which is in the form of a hook, and chain sections connecting the loop of one stirrup with the hook of the other stirrup around the wheel and detachable at one end therefrom.

3. An anti-skid device for wheels consisting of a pair of stirrups adapted to be seated upon a single spoke from opposite sidesthereof, each stirrup having a closed loop at one end and a hook at the other, andchain sections adapted to be passed over the tire of the wheel, each section bein connected at one end to the closed loop an adapted to be connected at the other end to the hook of the opposite stirrup.

4. An anti-skid device for automobile wheels consisting of a pair of U-shaped clips,

the extremities of which are bent out of the plane of the rounded portion thereof so that they may be seated upon the same spoke from opposite sides thereof and lie flat against the wheel felly with the extremities extending in the direction of the tire, the extremities of each clip being Formed with a closed loop in an open hook, and separate chain sections connected at one.end to the closed loop and adapted to be looped over the hook of the opposite clip and over the tire to hold the clips in position and to provide chain sections along the outside of the tire.

In testimony whereof I have signed my name to'this specification, in the presence of two subscribing witnesses, on this 6th da y of January A. D1915.
